Leetcode Next permutation

function generates the next larger sequence of the given sequence in alphabetical order until the entire sequence is reduced. The Prev_permutation function, in contrast, is the generation of the previous smaller sequence of a given sequence. The two principles are the same, only in the case of the reverse order, here only next_permutation as an example to introduce the algorithm.The following is based on the assumption that the same element does not exist in the sequence.

Shared_ptr source code

1 IntroductionAs we all know, because of its destructive replication semantics, auto_ptr cannot meet the requirements of standard containers for elements, so it cannot be placed in standard containers; if we want to automatically delete the objects indicated by the pointer elements that the container can hold when parsing the structure of a container, it is usually implemented in some indirect ways, which is cumbersome. The boost Library provides a new type of smart pointer shared_ptr, which sol

General question: Calculate the sum of all the approx. Numbers (that is, factors) of a ^ B and modulo them to 9901 and then output them. Solution: There are three main application theorems: (1) unique factorization theorem of integers: Any positive integer has only one way to write the product expression of its prime factor. A = (P1 ^ k1) * (P2 ^ K2) * (P3 ^ K3) *... * (PN ^ kN) where Pi is a prime number (2) divisor and formula: For the decomposed i
